Uniform URL handling on default archiver

As the archive URL depends on the current permission on the list it is not very persistent, as it is in general - http://www.w3.org/Provider/Style/URI - it is a good thing to keep the archive URL persistent, to allow for example much more easy external linking and integrating I have created some small patches against 2.1.11 which creates this feature.

To enable the patch
$ cd $MAILMANBASE
$ patch -p0 <Mailman+Cgi+private-py.diff
$ mv Mailman/Cgi/private.py Mailman/Cgi/archive.py
$ patch -p0 <mailman-2-1-11.diff
# Dirty way of hacking the right way, alter the Makefile if you want to do it nicely
$ sed 's/private/archive/g' cgi-bin/private > cgi-bin/archive
$ chmod +s cgi-bin/archive

If terms of keeping the old links working, this apache config will do the trick

RewriteEngine on
RewriteRule ^/pipermail(.*) /mailman/archive$1 [L,R=301]
RewriteRule ^/mailman/private(.*) /mailman/archive$1 [L,R=301]

If you want me to port it to 2.2 or 3.0 please let me know.
